Frequently asked questions
Does converting AAC to AIF improve the sound?
No. AIF is uncompressed PCM, but the source AAC is already lossy, so the AIF simply stores that same audio without further loss. It preserves what is there; it cannot restore detail AAC removed.
Why convert AAC to AIF?
AIF (AIFF) is Apple's uncompressed format widely used in professional audio editing and production, where an uncompressed working file is preferred. Converting gives you that editable, full-quality-as-stored PCM file.
Where will an AIF file open?
On Mac it opens in QuickTime Player or Music; on Windows use VLC or iTunes. Windows Media Player does not support AIFF, so a cross-platform player like VLC is the safe choice there.
Why is the AIF so much larger than the AAC?
AIF stores audio uncompressed, so files are large, roughly the size of the equivalent WAV. The AAC's compression is undone, which raises size without adding audible quality.
